GRINDING-MILL.

SPECIFICATION forming part of Letters Patent No. 227,465, dated May 11,1880.

Application filed June 23, 1879.

Fig. 3, an edge view; Fig. 4, an inside view of one-half of the case;Fig. 5, a plan of the fixed rings; Figs. 6 and 7, details of the hub E;Fig. 8, a plan of the movable grindingring; Fig. 9, an edge view of thesame. Fig.

' 10 is a section taken at line as of Fig. 4. Fig.

11 is a side elevation with one side of thecase and fixed ring connectedtherewith removed. Fig. 12 is a detail. Fig. 13 is a vertical crosssection.

This invention relates to that class of grinding-mills which aredesigned to be operated through the action of a windmill, giving to themovable grinding-rim g an intermittent rotary movement; and it consistsin the devices which are hereinafter claimed and described.

In the drawings, A represents the case, which consists of two parts, BB, which are alike and can be cast from the same pattern. The upper partof each half B. of the case 3 forms one-half of a hopper, O, and theedges of the two halves of the case do not come together except at thetop. a are lugs on the inside of B B. D D are grinding-rings, oneon theinside of each half of the case. They are cast separate from the case,and are held in place by lugs 12 on the periphery, which fit between thelugs a, or some of them. These rings are not complete, a space, 8, beingleft for the passage of the grain, as shown at Figs. 5 and c is a boltwhich passes through both parts of the case. E is a hub loose on theboltc. It is provided with two flanges, one on each side, which extendunder the stationary grinding-rings D D. d are lugs on the periphery of5 the hub E.

F is a loose grinding-ring. It has three recesses, e, in its inner edge,with which three ofthe lugs d engage. The remaining lugs d serve tocarry in grain from the hopper. The hub E and loose ringF rotatetogether. f are ratchetteeth on the outer edge of the loose grindinggagewith the teeth f. j are cog-teeth on a portion of the periphery of G. kis an arm on the ring G. It is provided with a series of holes, and toit the reciprocating rod of a windmill can be connected.

6 is a pinion on a shaft which has its bearings in the two walls m m,which extend across the hopper, the pinion being between these two wallsand covered by the flanges on the upper edges thereof. The teeth j on Gen gage with the pinion Z. The shaft n, on which this pinion is placed,extends into the hopper C on each side,and is provided with one or morearms, 19, which serve the purpose of agitating the grain in the hopper,which grain passes'through the passages s, and through the open space inthe stationary grinding-rings, part going between the movable grinder Fand one of the stationary rings, and part between the movable ring andthe other stationary ring, there being two passages from the hopperleading to opposite sides of the central movable grindin gring F. Thegrain falls upon the periphery of the hub E, which keeps it between therings. 4* are cars on the case to receive bolts for securing the mill toany suitable frame-work.

The loose grinding-ring F is allowed to move laterally on the lugs cl onthe hub E, thereby avoiding all cramping, which is liable to occur whenthe grinding-rings are rigidly fastened to a shaft. The several partsare held together by the single bolt 0, which can be tightened orloosened to make the mill grind fine or coarse.

The operation is as follows: The reciprocating rod of a windmill orother power is 'to be attached to the lever la in any suitable manner,but so that the movement of such rod will give to the ring Ga vibratorymovement; then, through the pawl h, which engages with the ratchet-teethf on the movable grinding-ring F, when the lever -ring G is moveddownward, or in the direction of the arrow of Fig. 2, the pawl engageswith the teeth on the yielding ring and communicates motion to it. Onthe upward or return movement of the lever-ring the grinding-ringremains stationary. Thus the action of the mill gives to such movablegrinding-ring an intermittent rotary motion. At the same time the teethj will, through the pinion l, give a vibratory rotary motion to theagitators 1) in the hopper, preventing the grain from clogging.

I do not limit the use of my improvements to grinding-mills which areused in connection with a windmill.

The grinding-ring F can be operated by a continuous rotary motionthrough a pinion and gear-cogs on the periphery of the loose ring,instead of ratchet-teeth, and the agitators 19 might be operated bymeans of gear-cogs on the loose grinding-ring F.

What I claim as new, and desire to secure by Letters Patent, is asfollows 1. The combination of the ring G, provided with a pawl, h, andteeth j, with the pinion Z, agitators p, and movable grinding-ring F,substantially as and for the purposes specified.

2. The hub provided with lugs 62 on its periphery and having flangesextending under the stationary grinding-rings D D, in combination with amovable grinding-ring, F, having recesses c on its inner edge,substantially as and for the purposes specified.

3. The case A, consisting of two like parts, B B, each provided withlugs a on the inside, in combination with two stationary detachablegrinding-rings, D D, each provided with lugs 11 and central fasteningand pivot bolt, 0, substantially as and for the purposes set forth.

4. The hub E and loosely-attached grindingring F, having free lateralmovement between the stationary grinding-rings D D, and in combinationtherewith, substantially as set forth.
